How can I implement form validation in Vue 3 using Vuelidate?

To implement form validation in Vue 3 using Vuelidate, first install Vuelidate via npm. Then, set up your validation rules in your component.

What are some common validation rules I can use?

Common validation rules include required, minLength, maxLength, email, and numeric. You can combine these as needed.

Can you show me a code example?

Sure! Here's a simple example:

import { required, minLength } from 'vuelidate/lib/validators';

export default {
  validations: {
    form: {
      name: { required, minLength: minLength(3) },
    },
  },
};

This sets up validation for a name field.

How do I display validation errors in my template?

You can use computed properties to check for validation errors and display them in your template. For example:

<span v-if="!$v.form.name.$pending && !$v.form.name.required">Name is required.</span>
